AUTOMATIC PUMP AND BOILER FEEDER.

Application mea April 7, y1923. seriaim. 6301559.

To all whom t may concern Be it known that I, VINonN P. McVoY, a citizenof the United States, residing Yat lriobile, in the county of Mobile andState of Alabama, have invented certain Vnew and useful Improvements inAutomatic Pump and Boiler Feeders, of which the following is aspecification.

rIhis invention relates to pum s, and more particularly to that class odevices designed as a boiler feeder, and it has for its object primarilyto provide a simple and efficient and reliable device for dry kilns,steam heated plants, or for any other use or place where it is desiredto put the water of condensation back into the boiler without the lossof temperature.

It has for a further object to provide a device for this purpose whichshall serve the purpose of the ordinary steam trap, thus allowing of thedispensing of such trap, as it serves not only the same function as anordinary steam trap butL goes further and not only separates the waterfrom the steam but returns the water to the boiler Without materiallyreducing its temperature.

There are not any packing glands, stuifing boxes, screw stems, pistonrods or any other parts exposed or partly exposed; all the mechanism isenclosed and requires absolutely no lubrication, as it is constructed ofsuitable anti-friction metals so as to eliminate the necessity oflubrication. It also eliminates the stopping up of thekiln with coldwater due to steam traps not working properly. It will increase thetemperature of the kiln from 25% to 30% and sometimes even more. It willprolong the life of the boiler due to the feeding of the hot waterinstead of cold, reduces the consumption of fuel and increases theboiler power, yet will give practically no trouble or require attentionto keep it in working condition. The returned water of condensationserves to supply the boiler. It will eliminate the biggest portion ofmud and other impurities that are deposited in the boiler from the useof bad water, and it also acts as an insurance against low water atnight,

' as well as day.

It is capable of application to any boiler in a short time and withoutthe employment of yskilled labor. The engineer can readily see Vtheworking of the device; when the water rises in the glass themaspecification, and in which- Figure'l is a substantially centralvertical section with parts broken away.

Figure 2 is a side elevation with portions broken away and parts insection.

Figure 3 is a top plan with the base broken away. n

Figuret is ak vertical longitudinal section on the line 4 4 of Figure 3.

Figure 5 is a vertical section on the yline, 5-5 of Figure 2.

Figure 6 yis a detail perspective viewof i,

,Figure 7 is a section taken on the line 7-7 of Figure 2.

Figure 8 is a vertical transverse section on the line 8-8 of Figure 3.

Like numerals of reference indicate like parts throughout the severalviews.

Referring first to Figure 1, the cylinderk is showny at 1, and the base`on which it rests at 2. The base is provided with suitable means, asthe lugs 3 to receive the screws or bolts or other means employed tosecure the cylinder in position. In the present instance the lower endof the cylinder l is provided with the inwardly-extended flange 4, andthe base with the outwardly extended flange 5 on which the flange 4-rests as seen in Figure l, the base and cylinder being secured togetherby suitable means as the bolts 6 passed through thek said flanges 4 and5.

The base 2 is provided with the discharge pipe 7 having a check valve 8therein as seen in Figure l whereby the water of condensation from thecylinder l is conveyed to the boiler or boilers, not shown.

At its upper end the cylinder 1 has a broad horizontal extension as seenat 9 provided with holes 10 for the reception of bolts o1' the like l1which serve to secure in place thereon the hood or cover l2 which lll)Serves to protect the Working parts which :rre mounted on the extension9 as Will be readily understood from Figure 1.

At the upper end of the cylinder there is providedun inlet pipe 13 withcheek valve 14 for the inlet ot' the Water 'of condensation from the drykiln, radiators or other source.

The upper tuee of themember 5% has e i 6G which is adopted to engage the neer G17 on the topet the member if the movement o'f' the said memr( seen in Figure and itsstem Work in the th stem being provided with or channels G9 as t l thevulve being itted he vulve Chamber 7l from ssoge T2 neer the top to 'thesteam vu,-.e piston 73 59 et the stoom inlet 7e is en exhaust tension 9kand with its lower end open to the atmosphere, as seen in Figures 1, 2,4 and 8. This tubular member is provided with a valve seat 7 6 for avalve 77 provided with the longitudinal grooves 7 8,` all as seenclearly in Figure 8. This valve is provided with a slot or recess 79 inwhich is received the lateral projection 8Oy on the member 81 pivoted at82 on the member 83 which is rigid with the tubular member 75. The freeend of the member 81 is extended at substantially a right angle,l inthis instance being shown as curved to form the arm 84 which eXtendsacross the member 51 as seen in F igures`2., 3 and 7 and the under faceof this portion or arm 84 is tapered as seen at 85 in Figures 2 and 4 toengage in the notch 52 0f the slidable member 51 at predetermined times.It is shown as engaged in said notch in Figure 2, the roller 60 havingmoved out of the'said notch.

86 is a stop for the weight 36 when the latter is in the one position,`that seen in Figure 4. It may be secured in any suitable manner, in thepresent instance having one end seated in a recess 87 in the under sideof the plate 28- and its other end secured between the top of thecylinder and the cov-v er 42 by one of the bolts 11 as seen in Figures1, 2 and 4.

Integral with the lateral branch 59 of the steam inlet pipe 58 is thechamber 88 in the lower portion of which is a valve seat 89 for a valve90, see Figure 8, the bottom of the valve chamber being open to4 theinterior of the machine beneath the cover 12. The valve 90 has thedepending lug or the like 91 as seen in Figures 1, 2, 4'and 8 to beengaged by the projection 62 on the gravitating member 54 as seen inFigure 2 where the said projection is engaged with the said lug 91 andhas raised the valve 90 from its seat. The upper portion of the valve 90is provided with a bleed or equalizing hole affording communicationbetween the space above the said valve and the lateral branch 59 of thesteam inlet pipe 58 as seen in Figures 2, 4 and 8, this bleed 92affording communication between the space above the steam inlet valve 90and the chamber 88, as Will be best understood from Figures 2, 4 and S.

The valve chamber 88 is provided with a removable closure 93 and the topof the chamber 68 is provided with a removable closure 9.4, as seen inFigures 2, 3 and 4 for an obvious purpose.

1n use, the inlet pipe 13 is connected up with the dry kilns or theradiators of a heating plant, or other' source of water of condensation,the discharge pipe 7 is connected up with the boiler to convey the waterof condensation thereto, and the pipe 95 is connected with the steamspace of the carrying with it the weight-36 by reason ot the engagementoi they shoulders 35 with the lugs 41 and 42 of the weight k56 as shownin Figures 3 and 4. Then the further movement of the float will move thearm 22 to such a point that the Weight v86 will be thrown or brought upgradually till its center of gravity passes the vertical when it fallsof its own weight and rests upon ythe counter balance 43. lWhen theweight is in the position in which it is shown in Figure 4 the lug 42 isresting against the shoulder 48 of the rocker arm 45 as seen in Figure4, the weight not being supported by the arm or lever 22. As the oatrises and moves the arm 22 the shoulders 35 of the said arm are broughtinto contact with the lugs 41 and 42 of the Weight and continuedmovement brings the weight into its vertical position, but in themeantime the counter balance 43 has struck the ,extension 9 and comes torest. the centre it falls upon the counter balance and is theresupported, the spring buffer 40 cushioning the stroke. It will beunderstood that the iniow of the Water of condensation from theradiators or other source gradually causes the iioat, the same beingguided upon its stem, to rise. After the weight 36 passes the cent-rc itfalls for a short distance and then the lug 42 coming in contact withthe shoulder 47 of the rocker arm 45 and moving the rocker arm on itspivot forces the member 51 to the right in Figure 4 and the roller 60 isforced upward Then the weight 36 passes out of its notch 52 and theroller then rides n upon the upper edge of they said member 51 into theposition seen in Figure 2. This forces the portion 63 of the member 56upward til-l it contacts with the stem of the pilot valve 65, forcingthe same upward and unseating the said valve, allowing the exhaust ofthe pressure above the steam valve 90 to pass through the passage 72 anddown the grooves 69 of the stem and out through the passage 74 to theinterior of the pump, as will be readily understood from Figures 2 and4. This actuation or' the valve 65 occurs just before the steam valve 90is unseated so as to relieve the pressure from above the same so thatthe steam valve may be readily unseated by the steam pressure from theboiler acting upon the under side of the piston portion 73 ofthe steaminlet valve 90; The

meinber 5l havingbeen moved so that its end 53 is out of contact Withthe `gravitating member 5% the latter falls into the position shown inFigure 2 and the portion 62 thereo comes under the lug` 91 of the valveand the valve is thus held in its open or raised position. The steamfrom the boiler, enterthrough the pipe 95 flows into the cylinder on topot the water that has accumulated therein forcing the same out throughthe outlet 7 to the boiler, the float gradually ita-lling with theWater. rlhe gravitating member oil serves to retain the steam valve inopen position notwithstanding' equalize.- tion ot the pressure upon bothsides ol the valve, after the first rush ot' steam to unseat the valve.

As the float falls it moves the arm or lever 22 downward a shortdistance before it picas up the Weight, by reason of the space betweenthe shoulders 3l and 35 being much greater than the thickness ot the lui4-2 on the opposite sides ot the iv i Then the inrushing steam raisesthe stes; valve 90 from its seat the valve le matieally closed and theinloiv of the Water of condensation stops. This valve remains closedtill the cylinder is empty. lWhen the steam enters and lifts the steamvalve 90 the pressure on top of the Water the cylinder l forces open thevalve 8 and the Water flows to the boiler, until the cylinder l isemptied, or practically so, that is, till the float has reached itslowermost position.

After the oat has fallen a prescribed t tance it picks up the Weight,that is shoulders 34 engage the lugs i-l and 42 on the Weight and bringsthe Weight to its ve tical position, the float then being` pra-cticallyat the bottom of the cylinder as seen in lligure l. `When the iloatmoves just fraction more the Weight falls by its oivn Weight and strikesthe member 86 as seen in Figure" it. vWhen the Weight falls the member5l is moved so as to assume the position shown in Figure Ll, the roller60 falling into its notch 52 and at the same time the rounded end 53 ofthe member 5l engages the adjacent portion o'l the gra iugmember 54 andknocks it out from mi the lug` 91 on the valve and the latter falls toits seated position, thus shutting` oil the steam. lt is to beunderstood that the valve 65 is also seated as the pats are returned totheir normal position. During the movement the arm Se riding upon themember 5l is forced out of its notch and up on top of the member 5l asseen in Figure l, this raises the valve 77 the escape of any air thatmay be accumulated in the radiators or dry kilns. rlhe steam remainingin the cylinder l will condense till it is at a point less than that inthe radiators or kilns.

from its seat, allowing" By meL ze .faechaniszi uf dos'eri am cnao toopen a valve rrea area than otherwise could be done, ano.

which is necessary in order to obtain rapid movement and emptying or'the cylinder, being limited to space and Weight. is to be noted thatcounter balance counterbab ances the lever 22, the arm 1S, the floatstem lo, and parts carried thereby, and at the same time upon the returnmovement of the Weight it does not add to the original Weight as theoriginal weight picked up it an angle off substantially 1li@ and thenlie counterbalance is picked up but adds no ertra weight. The arm 22 andthe Weight Je are moved together to a point of ease before picking` upthe counter balance, and at that point the two move as easily did theWeight 36 the start. The arm .42., 'the vv `ight ad the counterbalanceare all ted on the bushing, and have loosely moun mov l pendently o?each other. l

ent im y is to be noted tnat the members ot the piel:- up device are allloosely mounted on the shaAU so as to insure ease of movement.

Modifications in detail, proportion or etc., may be resorted to Withoutde- 'ig :trom the spirit ot the invention or icing any ot itsadvantages.
